我有一个函数可以进行API调用,并根据第一个API调用返回的内容进行第二个API调用。但是第一个API总是返回undefined
getTotalCount = async () => {
const { showCountCallBack, showCount } = this.props;
try {
const response = await showCount();
const count = isEmpty(response.result);
if (count) {
console.log(" success");
} else {
showCountCallBack({ ...this.state });
}
} catch (e) {
console.log("error");
}
};
describe("component", () => {
let shallowComponent;
let shallowComponentInstance;
const showCountMock = jest.fn(() => Promise.resolve({ result: [] }));
const showCountCallBackMock = jest.fn(() => Promise.resolve({ result: [] }));
beforeEach(() => {
showCountMock.mockReset();
shallowComponent = shallowWithTheme(
<Component
showCount={showCountMock}
showCountCallBack={showCountCallBackMock}
/>
);
shallowComponentInstance = shallowComponent.instance();
});
it("viewMapping", () => {
shallowComponentInstance.getTotalCount();
expect(showCountMock).toHaveBeenCalledTimes(1);
expect(showCountCallBackMock).toHaveBeenCalledTimes(1);
});
});
答案 0 :(得分:0)
奋斗了几个小时。我找到了原因。造成此问题的原因是Bad Request: JSON parse error: Expected array or string.; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Expected array or string.
at [Source: (PushbackInputStream); line: 1, column: 159] (through reference chain: com.xxx.MyObj["someDate"])
。
它也重置返回值。所以我刚刚从代码中删除了mockReset
。最好在这里使用mockReset
